And a light-transmitting member 5 disposed between the upper case 1 and the bottom wall 32 and closing the opening 33. Specifically, the light-transmitting member 5 includes a diffusion mask 51 for anti-glare, a prism sheet 52 for refracting light emitted from the light source assembly 2, the diffusion mask 51 being supported on the bottom wall 32 of the lower housing 3, the prism sheet 52 being interposed between the reflector 4 and the diffusion mask 51. The upper housing 1, the reflector 4 and the light-transmitting member 5 together define an optical cavity 6 in which light emitted from the light source assembly 2 is reflected.
